Katy Perry and John Mayer back together?

Musicians Katy Perry and John Mayer have reportedly rekindled their on/off relationship after nearly a year apart.

The former couple split last February but were spotted together again at a restaurant in the Sunset Tower Hotel in California on Thursday, sparking rumors of a romantic reunion.

A source tells the New York Post, “Katy Perry and John Mayer walked in together, arm in arm, and the whole room literally fell silent.

“Even Dimitri Dimitrov – Hollywood’s most famous maitre d’, who has seen everything – and Sunset Tower owner Jeff Klein, both stopped mid-sentence when John and Katy arrived, as if they wanted to announce to everyone in Hollywood they are back together.”

The meal in public reportedly took place days after they attended a friend’s dinner in Los Angeles last weekend.

Perry and Mayer initially began dating in 2012, following her divorce from comedian Russell Brand.

They split briefly in 2013, but revived their romance before calling off the relationship again last year.

Perry allegedly moved on to date producer Diplo, while Mayer remained largely out of the spotlight in 2014.
